As some of you may know, the FreePastry group at Rice University
is developing ePOST, a secure, decentralized, p2p email system.
The service is provided cooperatively by the user's desktop
computers, and ePOST provides better security and fault tolerance
than existing email systems. Email exchanged between ePOST users
is cryptographically sealed and authenticated and the service
remains available even when traditional mail servers have failed.
ePOST gives users plenty of email storage (users can use as much
as they contribute of their own disk space). Moreover, users
don't have to entrust their email to a commercial provider, who
may mine thier data, target them with advertisement or start
charging them once they're hooked. ePOST has been running as the
primary email system for members of our group for over a year.

ePOST works by joining a peer-to-peer network running a personal
IMAP and SMTP server on your desktop, which is only for your
email.  ePOST is backward compatible with existing email systems,
and your ePOST email address works just like a normal email
address - you can send and receive messages from non-ePOST
users.   Additionally, you can use your existing email clients
with ePOST, since ePOST provides standard IMAP and POP3 servers.

A few of other features of ePOST are:
- support for SSL connections
- a data durability layer called Glacier, providing
  durability with up to 60% member node failures
- support for laptops and machines behind NATs
- support for networks with routing anomalies

More information about ePOST is available at
http://www.epostmail.org/.

We now welcome additional ePOST users.  If you are interested in
seting up an ePOST account, please follow the installation
instructions posted at http://www.epostmail.org/install.html.
Most ePOST users have set up mail forwarding so that a copy of
incoming mails are kept on their normal mail server, in addition
to being forwarded to their ePOST account.  We recommend this
setup until ePOST is no longer in beta status, although we have
not found an instance yet where using this backup was necessary
to recover a lost email.

Also, please let us know if you are interested in running a local
ePOST ring at your institution.  Running such a ring allows
organizations to ensure all overlay traffic remains internal to
the organization, while maintaining global connectivity.  More
information on running an organizational ring is available at
http://www.epostmail.org/deploy.html.

We are currently collecting high-level statistics from all of the
ePOST nodes in our deployment for research purposes. These
statistics concern the number of overlay messages sent and the
amount of data stored on disk. We are not recording the plain
text of emails, nor are we examining which users are exchanging
emails.  If the collection of statistics would prevent you from
using ePOST, please don't hesitate to contact us, and we can turn
these features off for you.

Thanks again for your help, and don't hesitate to ask us any
questions, comments, or suggestions,

Alan Mislove, Ansley Post, Andreas Haeberlen, and Peter Druschel
